S. K. L. O: To observe how human beings have evolved over time W. S. L. O: To report findings To identify adaptive traits in humans as a species. To describe the known stages of human evolution. To compare modern humans with members of the same genus and family.

Adaptive Trait A genetic characteristic passed from parent give to their offspring. Inheritance Visible characteristics passed from parent to offspring. Evolution Usually genetic mutations caused by replication of damaged DNA or errors in replications. Natural Selection Visible characteristics caused by adaptations. Adaptation over time. Inherited Trait Adaptation The key mechanism of evolution. It determines which traits become more or less common and therefore are reproduced.

While you will not be examining these in detail, it is helpful to know about the building blocks of life for this unit. Cells are the building blocks of all living things. All living things are made up of cells. Amoebas have one cell. Humans have trillions of cells!

Chromosomes The nucleus of a cell contains chromosomes, which are made up of DNA carries the characteristics that we inherit. It is located in two places in the cell: the nucleus and the mitochondria. DNA can replicate and make copies of itself. When cells divide, each cell needs to have an exact copy of the DNA in the old cell. Genes are short sections of DNA that contain specific information. This is often called the genetic code. All the genes in the whole cell are called the genome.

The study of genetics and DNA is ongoing and scientists are making new discoveries as they research different aspects of DNA further. This quiz will test you on the percentage of DNA that we share with other living things.
